Background:

COG LEDs (Chip On Glass), which are LEDs built on glass or sapphire strips, have been known for years and are increasingly efficient. Their advantage is that achieving circular illumination is much easier with them than with SMD packaged LEDs, which often rely on opal covers to enhance light distribution with varying degrees of success. However, COG LEDs have the disadvantage that less light reaches the direction of the filaments. To solve this problem, Filament LEDs are placed in multiple positions under the cover, or we must choose an appropriate light source with the knowledge that less light reaches the filament direction.

This problem of “less light in the filament direction” could be solved if the LED filament were flexible, thus allowing shadowed areas to be eliminated by appropriate bending.

…and yes, there is a flexible filament LED.

Any LED strip can flicker or not. It depends on how it is operated.

How does this work?

The connector tab of the LED strip is wider than the space in the LED profile, so it doesn’t fit into the LED profile.
I can’t solder, so the only option left is to clip the connector clip onto the end of the strip.
But still, how can I get it into the LED profile?

either this way or that way…

Moreover, using a splicing element inside the aluminum profile is almost always feasible:

A newer LED technology that is referred to in various ways.
Some people also call this simply COB LED, as we read about COB LEDs that one of their more efficient development lines is building the chip on a ceramic substrate. Well, if they build it on glass, glass is also ceramic…

The essence is that COG LED, or Chip On Glass, means LED built on glass. The glass is cut into thin strips, so we can talk about LED filaments. The LED bulbs or candles made this way, at first glance, may seem like a thicker tungsten filament bulb is lit, which is why its most common international name is LED Filament. Some companies, instead of using this long name, refer to it as FiLED.

Below you can read the measurement results of practical examples.

If you buy an RGB LED strip, you will see that a 5-meter roll has about 10 cm of 4-core connecting wire. This wire has a cross-section of 4×0.2mm².
RGB LED strips consume 6W, 10.8W, or even 14.4W per meter, depending on the type. For example, a 5-meter roll with a nominal consumption of 72W also has a 10 cm long 4×0.2mm² cross-section connecting wire. One might think that if we want to install RGB lighting in a room, we can run the connection anywhere with such a cross-sectional wire, as long as we don’t exceed 72W consumption. This reasoning is flawed because the longer the wire, the higher its resistance, which means the LED strip will receive less voltage and will shine dimmer. To operate a 5-meter 72W LED strip, you need to ensure 6A at 12V.

The article also addresses the resistance of the LED strip. The farther the LED is from the power connection, the dimmer it will light. This issue is also considered below.

Let’s look at some practical examples:

The question is not just whether the LED flickers, but also, if it does flicker, how much does it flicker?

It has become a habit to check with our mobile phones whether the selected LED lamp flickers or not. As if we only expected perfection from the LED. It’s better to know that traditional bulbs flicker too, as do halogens.
Why doesn’t this bother anyone? – or did it bother us, but we didn’t have a choice back then. Those who still choose this don’t care about the issue at all.
We will skip the introduction of compact fluorescent lamps.

From left to right in the picture above, we can see the following E14 base light sources:

• 6 Watt SMD LED opal candle
• 4 Watt COG LED candle
• 6 Watt SMD LED opal candle
• 40 Watt traditional incandescent candle
• 28 Watt halogen incandescent candle
• 2 Watt COG LED candle

The online store offers over 600 types of easy, so-called retrofitted LED strip sets. These sets are packages selected from the store’s offerings, so if someone wants to add mood lighting with an LED strip afterward, they won’t need to search for accessories. These kits are designed so that you simply connect the components, stick the LED strip, fix the power connection point, plug the power supply into the outlet, and the LED strip will light up.

Additionally, you can choose from non-switch and about 10 types with switches, dimmers, infrared, or radio frequency remote controls. Options include warm white, cool white, red, yellow, green, blue, purple, or RGB (adjustable color) and RGBW. They range from 1 meter up to 10 meters, in 1-meter increments. If you need a non-standard length, choose a longer strip and cut it shorter in segments of three LEDs, close to the required length. For white LED strips, you can choose from 3 brightness levels, single-color strips have one, and for RGB and RGBW, there are two brightness options. Moreover, in the case of RGBW, the white chip is available in 3 color temperatures.
